[test] Fix unittest_i18n to run properly with "pytest -t" (closes #5576169)
When running "pytest -t", many tests modules will be imported and run
within a single python process. unittest_i18n fails when run after tests
such as unittest_webtest.py or unittest_httptest.py.
The main reason is that unittest_i18n does various tricks to add a test
cube to the search path, which badly fails when a previous test module
has already loaded "stuff" (for lack of a better word).
Instead, let's just call the 'i18ncube' command with subprocess.
The change from logilab.common.testlib to unittest is not directly
needed, but comes as a free cleanup with the above changes.
